We are facing 5 hours slowness in the script icxr12mi.sql and as per the note (Performance Issue With icxr12mi.sql When Applying R12.1.1 Maintenance Pack Patch 6678700 to Upgrade from 11.5.10.2 to R12.1.3 [ID 1366569.1]) . We need to create index on the table MTL_ITEM_BULKLOAD_RECS . How can I stop adpatch and create the index and start adpatch to continue from the same place of the script icxr12mi.sql .

Note: Keep in mind that the time that it takes on online index build to complete is proportional to the size of the table and the number of concurrently executing DML statements. Therefore, it is best to start online index builds when DML activity is low.
